Trina, I have made things in the past where I needed to have a flexible support and what I used were the banding straps from the lumber pallets at the Home depot store. As long as the pocket they fit in provides the shape they will support a pretty good load. Go to any building products or other store where they receive products on pallets. The strapping they use to secure the product to the pallet is about 3/4" wide reinforced plastic. It is easy to work with and most places will be glad to give it to you for free. Hope that helps Ken Nyren [Posted in FML 6649]
